General Information

e.hormone 2001 was lengthened in response to feedback from last year's successful meeting. This gave us a full three days to address important issues and foster collegial interaction. Key social and scientific events were interspersed throughout the conference.

"The conference was excellent in all aspects: planning, organization, speakers, and environment. I especially appreciated the theme of many of the presentations of signaling across organisms and the susceptibility of numerous systems from environmental hormones. I was very impressed by the topic sessions, representation from European and Asian scientists, and the caliber of the talks."
